is provided on the side of the flange 2 with a nut 8 and a jam-nut 9. On the other end. of each bolt in place of the usual head I provide a T-head 10, as seen in Fig. 1V.

The clamp shown in Fig. Ill consists of a handle 11, a curved stem 12, and a yoke 13. the two arms of which are similarly curved,

' as seen in Fig. Ii, so that while the yoke 13 straddles the bolt the curved arms each embrace one end of the cross-piece of the T-head. The side of each of these curved arms which is adjacent to the flange 3 is provided with a cam-surface 15, so curved that when the clamp is in the position of Fi 11 the extreme extension of the cam is below the center line of the bolt 7 whereby the tension of the bolt tends to hold the clamp in a condition of stable equilibrium in the position shown with the end of its curved stern pressed in against the felly.

For the purpose ofretaining the tire in place all of the bolts are inserted in the felly, and for each one a clamp, such as I have described, is inserted, with its arms beneath the T-head and with its handle resting against the inneredge of the folly. In this position the nut and jam-nut of the bolt are tightened, the tension thus created holding the clamp lirnily in place. When now it is desired to remove the tire, the handle on each clamp is grasped, and by pulling it toward the outside of the wheel the cams on the back of the arms of the clamp are drawn across the centerline of the bolt and the clamp removed from the wheel. The T-head on each bolt is then turned to a radial position, so as to register with the slots in the flange 3, which may thereforebe immediately removed, the T-hcads passing through the slots. To replace the flange, the operation is reversed. Ordinarily noloosew ing of the out 8 is required to etl'ect this operation, and consequently the remov: l and replacement of the flange can be eliected very much more rapidly than by devices heretofore used.

Having thus described my invention, 1 V

bolt whereby the flange is secured toZtho folly of the wheel, and a removable clamp, inserted' betwo'ei'l the flange and the bolt, substantially as described.

2. Afastening device for a detaehablefiange of a rubber-tired Wheel Which consists of bolts whereby the flange is secured to the telly of the wheel; 'l'heads upon said bolts; radial slots in the flange; and removable clamps, inserted between the flange and the T-heads of the bolts, substantially as described.

3. A fastening device for a detachable flange of a rubber-tired wheel which consists ofholts whereby the flange is secured to the telly of the wheel; and a clamp for each bolt having a cam-surtace which normally rests in a position of stable equilibrium in relation to the center line of the bolt, but which when removed allows the flange to be detached from the bolt, substantially as described.

4. A device for retaining the rubber tire on a Wheel which consists of a removable flange attached to one side of the felly of the wheel by means of bolts; T-heads upon said bolts; radial slots in said flange; and a clamping device for each bolt provided with a yoke-picce the arms of which embrace the ends of the T-head and are provided with cam-surfaces on the side resting against the flange, substantially as described.

In testimony whereof I have he reuntc signed my name, at Philadelphia, in the county of Philadelphia and State of Pennsylvania, this 25th day of April, 190d.
